Ozone therapy for patients with COVID-19 pneumonia: Preliminary report of a prospective case-control study.

Background: There is still no specific treatment strategies for COVID-19 other than supportive management.

Design: A prospective case-control study determined by admittance to the hospital based on bed availability.

Participants: Eighteen patients with COVID-19 infection (laboratory confirmed) severe pneumonia admitted to hospital between 20th March and 19th April 2020.

Potential Role of Oxygen-Ozone Therapy in Treatment of COVID-19 Pneumonia.

BACKGROUND Pneumonia caused by coronavirus originated in Wuhan, China in late 2019 and has spread around the world, becoming a pandemic. Many patients deteriorate rapidly and require intubation and mechanical ventilation, which is causing the collapse of healthcare systems in many countries. Coronavirus infection is associated with extensive lung inflammation and microvascular thrombosis, which can result in hypoxia.

Neuromyelitis optica spectrum disorders: Comparison according to the phenotype and serostatus.

Objective: To (1) determine the value of the recently proposed criteria of neuromyelitis optica (NMO) spectrum disorder (NMOSD) that unify patients with NMO and those with limited forms (NMO/LF) with aquaporin-4 immunoglobulin G (AQP4-IgG) antibodies; and (2) investigate the clinical significance of the serologic status in patients with NMO.

Methods: This was a retrospective, multicenter study of 181 patients fulfilling the 2006 NMO criteria (n = 127) or NMO/LF criteria with AQP4-IgG (n = 54). AQP4-IgG and myelin oligodendrocyte glycoprotein immunoglobulin G (MOG-IgG) antibodies were tested using cell-based assays.
